Microsoft: data leak

There was a major data breach at Microsoft, and the company's customer data was potentially publicly accessible. A security firm discovered a misconfigured server with the data freely on the Internet and notified Microsoft in September.

The event may have affected some of Microsoft's customers, whose email addresses may have been leaked along with other data.


Security researcher Kevion Beaumond announced the incident to Microsoft in a series of tweets.

Security company SOCRadar searches for open servers on the Internet with the BlueBleed project. In September 2022, it also discovered misconfigured Microsoft servers that were accessible over the Internet. Security researchers published the article Sensitive Data of 65,000+ Entities in 111 Countries Leaked due to a Single Misconfigured Data Bucket, but without naming the company:

“SOCRadar discovered that sensitive data of 65.000 entities was made public due to server misconfiguration. The leak includes Proof of Execution (PoE) and Statement of Work (SoW) documents, user information, product orders/quotes, project details, Personally Identifiable Information (PII) data, and documents that could indicate intellectual property.

After SOCRadar alerted the company to the issue, the server was immediately secured. Microsoft published the article Investigation Regarding Misconfigured Microsoft Storage Location about this incident. Confirms that it was notified by SOCRadar security researchers of a configured Microsoft endpoint on September 24, 2022.

This misconfiguration resulted in unauthenticated access to some business transaction data, the researchers report. These are transactions related to interactions between Microsoft and customers, such as the design or possible implementation and development of Microsoft services.

Business transaction data included names, email addresses, email content, company names, phone numbers, and possibly file attachments related to transactions between a customer and Microsoft or an authorized Microsoft partner. The issue was caused by an unintentional misconfiguration on an endpoint that is not used by Microsoft.

Microsoft said it found no evidence that customer accounts or systems had been compromised. Microsoft reportedly notified affected customers directly about the incident.
